Abstract: The invention relates to a mold for the production of dishes from powdered ceramic materials wherein two coaxial cylindrical dies are displaceable to generate with their end facing walls a cavity to be filled with the powdered ceramic materials, said cavity being peripherally completed by a displaceable die-box provided with a vertical conduit through which the ceramic material is fed into said cavity. An auxiliary die-box is provided sideways on said die-box, displaceable at least along one of said cylindrical dies, the lateral facing walls of said die-box and of said auxiliary die-box (16) being provided with annular grooves that in the closed condition of said lateral walls generate an annular cavity that may be registered in correspondence with said first-mentioned cavity of the mold, radially prolonging the latter and forming the peripheral border of the dish to be produced.
